Dust and pollution control
Airborne contaminants and particles of a certain size and hardness can damage the system. Some
of the most common contaminants are dust, smoke, ash, eraser debris, food crumbs, and salty air.
Mechanical filters on the disk array protect it by trapping large dust particles. Smaller particles can
pass through some filters, and can eventually cause problems in mechanical parts. Prevent small dust
particles from entering the computer room by maintaining its air conditioning system at a high static
air pressure level.
Your HP representative can help you determine if you need to be concerned about airborne
contaminants. HP strongly recommends your site be evaluated for metallic particulate contamination
before the system is installed. You should also periodically monitor for metallic particulate
contamination.
Metallic particulate contamination
Metallic particulates can be especially harmful around electronic equipment. This type of contamination
may enter the data center environment from a variety of sources, including but not limited to raised
floor tiles, worn air conditioning parts, heating ducts, rotor brushes in vacuum cleaners, or printer
component wear. Because metallic particulates conduct electricity, they have an increased potential
for creating short circuits in electronic equipment.
Over time, very fine whiskers of pure metal can form on electroplated zinc, cadmium, or tin surfaces.
If these whiskers are disturbed, they may break off and become airborne, possibly causing failures
or operational interruptions. For over 50 years, the electronics industry has been aware of the relatively
rare but possible threat posed by metallic particulate contamination. During recent years, a growing
concern has developed in computer rooms where these conductive contaminants are formed on the
bottom of some raised floor tiles.
